Luggage Racks and Backrest for BMW 1300 GS
if you have a BMW Vario Rack on your bike - use "Vario" 
if you have a BMW full black "Plastic" rack with 4 silver screws- use "Plastic" 
if your bike does not have either of these you can see if the SW Motech Adventure Rack will work with your model (swmotech.com)- if it does, use "Backrest and ADV Adapter Plates"
